State police said the teenagers knowingly ate gummy bears on Thursday morning that had been soaked in vodka.

“At the start of the day, while they're all hanging out in the cafeteria, (a student) had passed out some of these gummy bears that were soaked in vodka to a few other students,” said Trooper Stephen Limani. “It works well for the child because they're able to conceal the alcohol -- it sort of looks like a candy to the naked eye -- and they're getting the alcohol that they're trying to get the added effects.”

Charges of purchase, consumption, possession or transportation of liquor were filed with District Judge Mark Bilik.

The students have not been publicly identified because they're juveniles.

The Derry Area School District has not returned a call for comment from WTAE's Ashlie Hardway.

Limani, from the Greensburg state police station, said there was a similar issue at Hempfield Area High School last year.

“One of the things that has tendency to happen when it comes to kids, is kids have a tendency to talk to other children, and that's how this investigation started,” said Limani.

Pittsburgh police say they used evidence lifted from Mocospace after the suspect uploaded acts to the site. The girl told police that he knew she was only 13 and that he would stalk and harass her, waiting for her to get off the school bus.
